Is it weird I'm this happy?

No, I don’t smoke pot, and I’m not on drugs. But I feel like I’m always happy sometimes, and some of my friends think it’s weird, even my teachers. Like, in the morning, I’m not grouchy or quiet or anything, I’m happy and loud and cheerful. I’m always told that I’m really happy and I smile and laugh to much. Now, I am normally a loud person, but it’s not like I start a riot in the morning, I just happen to be a morning person. Also, I laugh a lot. Many people seem to think thats weird.

Is this really not that normal? Don’t hesitate to ask for more examples on my cheery attitude. I just need to know, is it so wrong to be happy?
